Korea launched a major reform to introduce performance-based budgeting into the government sector in the 2000’s. The Korean case is particularly interesting in that the government pushed the reform ahead very rapidly while other reforms in the budgetary system were also pursued concurrently known as the Four Major Fiscal Reforms, which provided an extraordinarily favorable environment for building an effective performance management system. Due to such a big push forward on a large scale, the Korean government was able to establish a comprehensive and robust performance management system in a short period of time. The Four Major Fiscal Reforms consisted of the establishment of a medium-term expenditure framework known as the National Fiscal Management Plan, introduction of top-down budgeting, establishment of the performance management system, and building of a digital budget information system.(The rest omitted)
